ENGLISH
• Charge the battery packs only in DEWALT
chargers.
• DO NOT splash or immerse in water or other
liquids.
• Do not store or use the tool and battery pack
in locations where the temperature may reach
or exceed 40˚ C (105° F) (such as outside
sheds or metal buildings in summer).
DANGER: Never attempt to open the
battery pack for any reason. If battery
pack case is cracked or damaged, do not
insert into charger. Do not crush, drop
or damage battery pack. Do not use a
battery pack or charger that has received
a sharp blow, been dropped, run over

result. Damaged battery packs should be
returned to service centre for recycling.

tool on its side on a stable surface
where it will not cause a tripping or
falling hazard. Some tools with large
battery packs will stand upright on the
battery pack but may be easily knocked
over.
SPECIFIC SAFETY INSTRUCTIONS FOR NICKEL CADMIUM
(NiCd) OR NICKEL METAL HYDRIDE (NiMH)
• Do not incinerate the battery pack even if it is
severely damaged or is completely worn out.
The battery pack can explode in a fire.
• A small leakage of liquid from the battery
pack cells may occur under extreme usage or
temperature conditions. This does not indicate
a failure.
However, if the outer seal is broken:
a. and the battery liquid gets on your skin,
immediately wash with soap and water for
several minutes.
b. and the battery liquid gets into your eyes,
flush them with clean water for a minimum
of 10 minutes and seek immediate medical
attention. (Medical note: The liquid is 25–35%
solution of potassium hydroxide.)
Battery Cap (fi g. A3)
A protective battery cap is supplied to cover the
contacts of a detached battery pack. Without the
protective cap in place, loose metal objects could
short circuit the contacts, causing a fire hazard and
damaging the battery pack.
1. Take off the protective battery cap (15) before
placing the battery pack in the charger
or tool.
2. Place the protective cap over the contacts
immediately after removing the battery pack from
the charger or tool.
WARNING: Make sure the protective
battery cap is in place before storing or
carrying a detached battery pack.
